Dragon by *GENZOMAN a dragon is a serpentine legendary creature. The Latin word draco, as in constellation Draco, comes directly from Greek. The word for dragon in Germanic mythology and its descendants is worm (Old English: wyrm, Old High German: wurm, Old Norse: ormr), meaning snake or serpent. In Old English wyrm means "serpent", draca means "dragon". Finnish lohikäärme means directly "salmon-snake", but the word lohi- was originally louhi- meaning crags or rocks, a "mountain snake".
